Kazan SEO AI Detector
Professional-grade AI content detection and semantic SEO analysis at zero cost.
Real-time linguistic fingerprinting to distinguish human creativity from machine-generated text.
AI Detector by SpellCheck.nz is a high-precision linguistic analysis tool optimized for the 2026 digital ecosystem. It operates by evaluating the 'perplexity' and 'burstiness' of submitted text—two critical metrics that distinguish the predictable token distribution of Large Language Models (LLMs) from the more erratic, creative patterns of human writing. The technical architecture employs an ensemble modeling approach, referencing behavioral footprints from GPT-4o, Claude 3.5, and Gemini 1.5 Pro. Unlike many enterprise competitors that require heavy-duty subscriptions, SpellCheck.nz provides a lightweight, browser-based interface that processes character-level data in real-time. This makes it a preferred choice for New Zealand-based educators and international content managers who require immediate, friction-free verification of content authenticity. By 2026, the tool has refined its heuristic engine to account for 'AI-human hybrid' writing, providing a granular percentage-based probability score rather than a binary result. It integrates seamlessly with the broader SpellCheck.nz suite, allowing users to move from detection to grammatical refinement in a single workflow.
Calculates the complexity of the text; lower complexity scores indicate a higher probability of LLM origin.
